Abstract
In this paper a Quad-band diversity antenna with a small size of 48 × 28 × 0.8 mm3 printed on FR4 substrate is presented that consists of two same pentagonal-shaped patch elements. Four arc-shaped slots in the radiating elements are introduced to obtain the quad-band operation with good return loss. The antenna is designed for covering 5.91 GHz in IEEE 802.11 b/g/n standards, 7.40 GHz in C-Band, 9.18 and 10.72 GHz in X-Band. To achieve the lowest coupling between two elements, three structures for embedding elements are investigated. The prototype is fabricated, and measured results are in good agreement with simulated results. The final antenna accomplishes a weak mutual coupling below −29.2 dB in the all operational bands. Radiation characteristics, radiation efficiency and diversity performance such as diversity gain and envelope correlation coefficient of the final structure, are presented.
